[0038] 1. Materials and Methods

[0039] 1.1. Materials:

[0040] Fullerene micro-capsule powder prepared in the preparation example 1 (hereinafter referred to as fullerene micro-capsule powder), micro-capsule powder prepared according to the steps of preparation example 1 without the addition of fullerene (hereinafter referred to as blank micro-capsule powder), Kunming mice (male, 4-week old, SPF grade, body weight: 20-22 g, license No.: SCXK (Shanghai) 2017-0005), mice standard fodder, padding (purchased from Minhou County Wu's Laboratory Animals Trading Co., Ltd.), eosin methylene blue agar media, Enterococcus media, MRS agar media, BBL agar media, and Beijing Red Star Erguotou (ABV: 56°).

[0041] 1.2. Methods:

[0042] 40 Kunming mice were fed with the standard fodder for one week, and randomly divided into 4 groups by body weight, 10 in each group: blank group (fed with the standard fodder only), model group (fed with the standard fodder only), test group (fed with the fodder containing 10% (mass fraction, similarly hereinafter) of fullerene micro-capsule powder), and solvent control group (fed with the fodder containing 10% of blank micro-capsule powder). The mice were fed in different cages of a same room, received natural lighting, took food and water freely, and environment temperature was controlled within (22±2°) C, and relative humidity was controlled to 60%. The mice in the model group, test group, and the solvent control group were administered intragastrically 1×10.sup.−3 ml/kg BW Beijing Red Star Erguotou during the feeding process for 8 weeks, then these mice were killed by cervical dislocation and dissected to collect cecal contents of the mice for flora detection. The mice in the blank group were fed with the standard fodder only without the intragastric administration of Beijing Red Star Erguotou during the feeding process, 8 weeks later after feeding, these mice were killed by cervical dislocation and dissected to collect cecal contents of the mice for flora detection.

[0043] 0.1 g of cecal contents were taken and put to a 5 mL of sterile centrifuge tube, and added with sterile saline solution for dilution according to a ratio of 1:9 (m/V), and then subjected to vortex mixing well to obtain 10.sup.−1 diluent. The 10.sup.−1 diluent was subjected to gradient dilution until 10.sup.−4, 10-5 and 10.sup.−6 diluent were obtained. 500 ul of three kinds of diluent were respectively taken and coated onto an eosin methylene blue agar medium (Escherichia coli was detected, and cultured for 24 h at 37° C.), an MRS agar medium (Lactobacillus was detected, and cultured for 48 h at 37° C.), an Enterococcus faecalis agar medium (Enterococcus faecalis was detected, and cultured for 48 h at 37° C.), and a BBL agar medium (Bifidobacterium was detected, and anaerobic cultured for 48 h at 37° C.), and 3 parallel tests were performed for each degree of dilution, and the whole process was completed within 30 min. Culture was performed according to the above culture conditions, and then colony counting was performed, and the result was expressed as 1 g (CFU/g). Characteristic bacterial colonies were picked for ecological biochemical experiments first to identify the bacterial genus before colony counting.

[0044] 2. Statistical Treatment

[0045] The statistical analysis of all the data was performed with GraphPad Prism5 and SPSS22.0 software, and the result was represented by “mean value ±standard deviation”, and variance analysis was taken for comparison. p<0.05 shows a significant difference, and p<0.01 shows a highly significant difference.

[0078] Daily gain: body weight of fasting piglets was weighed at 9:00 in the early morning of the 1st and 60th days during the test, and average daily gain (ADF) during the whole test was calculated; ADF=total weight gain of the pigpen/(number of pigpen piglets x number of test days).

[0079] Food consumption: a group was set as a unit during the test to accurately determine and record the daily feeding amount of the fodder, and to calculate the average daily feed intake (ADFI); ADFI=total food consumption of the pigpen/(number of pigpen piglets x number of test days).

[0080] Material-to-weight ratio: the material-to-weight ratio (F/G) in each stage is calculated according to a ratio of ADFI in the whole test period to ADG; F/G=ADFI/ADG.

[0081] Diarrhea rate (%)=100×[total number of diarrhea piglets in each group during the test period/(total number of piglets in each group x total number of test days)].

[0092] It can be seen from Table 7 that compared with the blank group, the number of Escherichia coli has no significant difference (P>0.05) when the weaned piglets were fed with fullerene micro-capsule powder for 20 d; after feeding for 40 d, compared with the blank group, the number of Escherichia coli has significant differences (P<0.05); contents in each intestinal tract are consistent; when the weaned piglets were fed for 60 d, compared with the blank group, the number of Escherichia coli has highly significant differences (P<0.001) and contents in each intestinal tract are consistent.

[0093] It can be seen from Tables 6 and 7 that compared with the blank group, starting from feeding the weaned piglets with fullerene micro-capsule powder for 40 d, the number of lactic acid bacteria in the test group increases significantly, and contents in each intestinal tract (duodenum, jejunum, ileum, cecum and colon) are consistent. The number of Escherichia coli increases significantly and highly significantly increases up to 60 d.

[0121] R1 is fitted by 3 times of sampling before taking the fullerene micro-capsule powder; R2 is fitted by 12 times of sampling in the process of taking the fullerene micro-capsule powder; R3 is fitted by 3 times of sampling after taking the fullerene micro-capsule powder.

[0122] 2.3.2 Alpha-Diversity Analysis

[0123] Abundance index of flora includes an ACE index and a Chao1 index; the larger the ACE index and the Chao1 index are, the higher the abundance of flora is. Diversity index of flora includes a Shannon index and a Simpson index; the larger the Shannon index and the Simpson index are, the higher the diversity of community is. The obtained results are shown in A-D of FIG. 4.

[0124] It can be seen from A-D of FIG. 4 that after taking fullerene, the ACE index and the Chao1 index increase obviously relative to that before taking; the abundance R3>R2>R1; R6>R5>R4; R12>R11>R10; R15>R14>R13; R18>R17>R16; because the classification is subjected to personal distribution, and index clusters a same individual, and has universality among the crowd, it indicates that fullerene may improve the abundance of flora. After taking fullerene, the Shannon index and the Simpson index increase obviously relative to those before taking fullerene; the abundance R2>R3>R1; R5>R4>R6; R8>R9>R7; R11>R12>R10; R17>R18>R16, and experiment comparison is a single factor; therefore, it may indicate that fullerene may increase the diversity of intestinal flora.

[0125] 2.3.3 Analysis on the Composition and Distribution of Intestinal Microecology

[0126] The bacteria whose abundance at the levels of Phylum, Order, Family and Species ranks the top ten were subjected to distribution analysis; where, the distribution result of the flora abundance at the level of Phylumis shown in Table 9 and FIG. 5; the distribution result of the flora abundance at the level of Order is shown in Table 10 and FIG. 6; the distribution result of the flora abundance at the level of Family shown in Table 11 and FIG. 7; the distribution result of the flora abundance at the level of Species is shown in Table 12 and FIG. 8.

[0127] Each flora in Table 9 and FIG. 5 is as follows: Nitrospirae, Euryarchaeota, Acidobacteria, Tenericutes, Fusobacteria, Unidentified-Bacteria, Actinobacteria, Bacteroidetes, Proteobacteria, and Firmicutes. Each flora in Table 10 and FIG. 6 is as follows: Unidentified-Bacteria, Coriobacteriales, Selenomonadales, Enterobacteriales, Lactobacillales, Bifidobacterium, Erysipelotrichales, Xanthomonadales, Bacteroidales, and Clostridiales.
